In this study, laser cladding and its applications are reviewed. First, the background of the technique and its important parameters are highlighted. Then, the control of the laser cladding procedure is criticized. As an example of the process, laser cladding of titanium alloys is investigated. Finally, applications of laser cladding on gas turbine engines, dies and drilling spindles, tools, and turbine blades are highlighted. © The Author 2023. Published by ARDA.

Outline With the fast development of laser claims and the decrease in the price of laser structures, laser material dispensation has added an increasing position in various productions such as aerospace, automotive, defense, and navy. In recent years, laser technology applications are gaining substantial attention because of their spread possibility for material dispensation for example laser and metallic coating. Laser coating is a mutual technology using design (CAD) and manufacturing sensors, robotics, and powder metallurgy. Laser plating uses a laser warmth basis to sum a skinny stratum of the anticipated metal onto a movable substrate. The accumulated stuff can be conveyed to the substrate by various approaches. The laser coating process offers an additive manufacturing and prototyping technique and allows complex components to be produced without intermediate steps. Laser plating proposes many compensations over traditional coating procedures such as arc welding and plasma spraying, with negligible distortion and improved surface quality. There is also a number of benefits to using this method as a rapid prototyping practice. Rapid prototyping can be utilized to yield part homogeneous structures and improved mechanical properties. Parts produced utilizing the method are close to net shape, nonetheless, often need post-processing. Because of its additive environment, laser plating can be practiced in a diversity of parts, tools, and innovative production to overwhelm the boundaries of current metal production machineries. This provides a number of advantages such as [1, 2]: reduced production time, improved thermal control, part repair, fabrication of a functionally rated part, and production of the smart structure. Notwithstanding its clear profits, laser plating is not hitherto extensively used in metallic coating applications. Though laser plating proposes some compensations over traditional production machineries, the procedure may besides have disadvantages such as quality differences. High asset price, low efficiency of laser sources, and absence of control in coating are drawbacks of this equipment. However, high-power diode lasers (HPDL) show countless industrial potential for utilization in metallic coating requests. In this study, laser cladding will be overviewed introducing laser cladding equipment, controlling of laser cladding process, laser cladding of titanium alloys as well as practical applications will be highlighted.
